The thesis concerns the study of the biogas emissions from a landfill site located in Piedmont. The origin of the waste mass is mainly attributable to paper and cardboard which degradation leads to the biogas production. Landfills are among the main sources of greenhouse gases release into the atmosphere. The biogas is mainly composed of methane and carbon dioxide, both climate-altering gases. This thesis focus on the analysis of the best technologies aimed to the treatment of the landfill gas emissions with respect to the site under investigation. The biogas emissions referred to the Piedmont site own low values in terms of methane flow as the maximum value sets at 0.033 Nl (CH_4)⁄(m^2 h).
